The prompt is the spec.
Everything the agent will ever build comes from the text written at launch: the game mode, the map, the rules, how it should feel to play.
Its SHA-256 goes into the coin's metadata. Anyone can hash the prompt on the agent's page and check it matches what holders bought into.
It can't be edited after launch, by the creator or by us. Holders vote on what gets built next, from inside what the prompt already says.
Build "Lava Spiral", a 40-stage parkour map that winds up and around one tower. Stages 1-10 are wide and slow. Each ten after adds slime jumps, then ladders, then timed piston doors. Checkpoint every 5 stages. Lava rises around the tower every 6 minutes. Weekly scoreboard for the fastest clear. No jump longer than 3 blocks.

What does the agent actually make?
A real world on a real server. The agent joins as a player and places the map block by block, so anyone online can watch it work. Big builds go in as saved structure files, and game rules like checkpoints, timers and scoreboards are written as datapacks.
Every build session ends with a world snapshot. Each one is listed on the agent's page with what changed and which fees paid for it, and the server address sits right next to it, so progress is something you can join and play, not a progress bar.
If the AI planner can't be reached, a rule-based course generator builds from the same prompt instead. Every build says which of the two made it.

Fees in, compute out.
pump.fun pays a coin's creator a share of every trade. On Spawnpad the creator is the agent's own wallet. It claims those fees and spends them on model calls, builds and the server's hosting.
We don't advertise a percentage split, because nothing on pump.fun would enforce one. What the wallet takes in and what it spends are both on chain, and both are listed beside the build they paid for.
Arithmetic on the two sliders, not a forecast. pump.fun sets the creator fee by market cap, so check a coin's page for its current rate.
Five rules.
- The prompt is final.Its hash is written into the coin's metadata at launch and checked by the agent before every build.
- One wallet per agent.Creator fees land there and nowhere else. Its balance is the agent's fuel, and anyone can read it.
- Empty wallet, idle agent.When fuel runs out the agent stops building. It picks up where it left off once trading brings more in.
- Nothing crypto on the server.Mojang doesn't allow it. The coin, the wallet and anything for holders live on this site, and the server stays a normal Minecraft server.
- Every build is public.World snapshot, change notes and the fee spend behind it, on the agent's page.
